Work History

Staked as Cro cl 1-41 (YA96297) in Sep/86 by R. Bilquist and optioned to Sirius Resources Corp, which carried out prospecting, chip sampling and geological mapping in 1987. Skukum Ventures Ltd tied on Bob cl 1-92 (YA98093) to the north and Kurt cl 1-52 (YA98188) and Hal cl 1-42 (YA98346) to the south in July 1987. Its successor Skukum Gold Inc carried out geological mapping, prospecting and geochemical sampling on the Bob, Kurt and Hal claims in 1988. In 1989, a similar program was carried out on the Kurt and Hal claims and blast trenching and chip sampling were carried out on the Bob claims.
The ERT zone (Bob cl 64) was restaked as Krista cl 7-12 (YB95978) in Aug/96 by B. Kreft, who added Krista cl 27-32 (YC08013) to the west in Aug/97 and completed reconnaissance prospecting at that time.

Capsule Geology

The Cro claims covered the contact between Paleozoic Nisling Assemblage metamorphosed schists and Early Eocene Skukum Group volcanics consisting of breccias, conglomerates and tuffs forming the Bennett Lake Cauldera Complex lying to the south. Jurassic or Cretaceous aged diorite has intruded the metamorphic rocks to the north. Quartz float and conglomerate sampled from along the schist/volcanic contact returned anomalously high Au and Ag with peak values of 300 ppb and 1.12 oz/t respectively.
On the Bob claims, disseminated to massive sulphides and manganese oxide form the matrix of a rhyolite breccia 10.5 m wide at the contact between the Jurassic or Cretaceous diorite and the Paleozoic metamorphic rocks. This area known as the 'ERT' zone is found at the headwaters of Crozier Creek. The sulphides include arsenopyrite, sphalerite, galena, chalcopyrite, stibnite and pyrite. The breccia strikes northwest and its associated geochemical anomaly appears to be offset along several northeast-trending faults. Channel samples across the ERT zone assayed 1.65 g/t Au and 410.7 g/t Ag over 5.0 m in Trench 89-1 and 0.89 g/t Au, 584 g/t Ag over 2.7 m in Trench 89-3.
On the Kurt claims, a series of 1.5 m wide quartz lenses containing traces of galena and pyrite extend over a strike length of 200 m (the 'T-Bird' zone). The veins strike ENE, dip moderately southeast, and cut propylitically altered quartz monzonite. Grab samples contained up to 4 945 ppm Pb, 440 ppm Zn and 30.8 g/t Ag. In the centre of the Kurt claim block, a 400 x 1700 m area with anomalous gold, silver, zinc and arsenic is associated with small vuggy fluorite-calcite veinlets and clay and sericite-altered volcanic rocks.
On the ridge at the west end of the claims, a quartz vein up to 5 m wide outcrops over a strike length of 700 m (the 'T-Bone' showing). The vein strikes northwest, dips northeast and returned assays up to 2.44% Pb and 77.2 g/t Ag from grab samples.
At the southwest corner of the Hal claims, a showing referred to as the 'Woody zone' consists of fluorite-quartz-calcite veins up to 4.5 m wide in a 20 m wide zone of rhyolite-sulphide breccia. Arsenopyrite, galena, pyrite and sphalerite occur along crackle fractures and in the breccia matrix. Grab samples contained up to 25 356 ppm As, 1 610 ppm Pb, 875 ppm Cu, 27.7 g/t Ag and 0.62 g/t Au. The presence of massive fluorite, crystal-lined vugs, silica replacements of bladed calcite, clay and silica alteration, and low silver to gold ratios suggest that the Woody zone could be part of a high level epithermal system.
Kreft re-located and re-sampled the ERT zone. Assay results substantiated previously reported values. Prospecting located a new showing, the Tre zone, 50 m southwest of the ERT zone. The Tre zone is a 1.8 m wide zone, of undetermined length, that consists of disseminated to massive sulphides and manganese oxide that returned assay values similar to the ERT zone. The Tre zone was found by following up a previously known soil anomaly. Kreft suggested that a small soil sampling and hand trenching program would provide a more accurate estimation of the zone and surrounding area¿s economic potential.
